Abstract: The present invention is a system and method for custom tailoring and manufacturing apparel by using numerous try-on apparels of differing, pre-determined dimensions to make a finished product. A system is used to keep track of the number of try-on apparels and each of their dimensions. As a consumer tries on one of these try-on apparels, a device associated with the system is used to collect the consumer's responses about fit. If one try-on apparel does not fit, the system suggest a next one to try, according to pre-defined rules. When a particular try-on apparel's fit has been approved for purchase by the consumer, this is reported to a manufacturing system, where a piece of apparel corresponding tothe dimensions of the approved try-on apparel is cut, stitched, treated, and shipped as a finished apparel.

Abstract: Un système permet de localiser et surveiller des dispositifs électroniques à l'aide d'un dispositif de sécurité qui est incorporé de façon secrète et transparente dans le logiciel, les programmes personnalisés ou le matériel d'une installation informatique. Ce système de sécurité provoque, de façon périodique et conditionnelle, l'appel d'un ordinateur central par l'ordinateur du client qui lui indique son numéro de série par l'intermédiaire d'une série codée de nombres sélectionnés automatiquement. Un système central de surveillance reçoit des appels de différents clients et détermine lesquels accepter et lesquels rejeter en comparant les numéros de séries de clients décodés avec une liste définie et actualisée de numéros correspondant à des ordinateurs dont on a signalé le vol. Seuls sont acceptés des appels provenant de clients figurant sur cette liste. L'ordinateur central obtient aussi simultanément l'identité d'appel du client appelant pour déterminer la localisation de l'ordinateur du client. L'identité d'appel, qui indique la localisation de l'appareil volé, et le numéro de série sont alors transmis à un service de notification pour faciliter la récupération de cet appareil. Ce système de sécurité reste caché à l'utilisateur et résiste efficacement aux tentatives de le désactiver.

Abstract: A drive system and a method of operating such a system are specified. The drive system comprises at least two drive groups having a plurality of drive controllers of controlled drives. The drive controllers of a drive group are synchronized via a drive bus by means of a local synchronization clock, and the local synchronization clocks are made equal to a global synchronization clock via a drive data network connecting the drive control means. The plant-wide synchronization of the drives via a global signal enables a drive system to be equipped with a virtually arbitrary number of drives. As a result of the fact that the desired values are preferably likewise transmitted synchronously, based on the global synchronization clock, between the drive control means via the drive data network, it is also the case that no time errors occur during the desired value transmission. The invention is preferably used for rotary printing machines.

Abstract: Chilled or shelf stable beverage products which are physically stable, visually opaque and do not precipitate over time are disclosed. These products contain from about 5 to about 99.8 % milk, from about 0.05 to about 0.8 % of a food stabilizer and a food acid. The first step of the process involves mixing milk with a food stabilizer under high shear mixing conditions to form protein/stabilizer particles having a median particle size of less than about 0.8 microns. Then, while still maintaining the particle size of the protein/stabilizer particles at less than about 0.8 microns, the protein/stabilizer mixture is acidified to a pH ranging from about 3.2 to about 4.5. In order to maintain the requisite particle size of the protein/stabilizer particles during the acidification step, the protein/stabilizer mixture is maintained under high shear mixing conditions at a temperature ranging from about 4 to about 30 ~C.

Abstract: A method for attenuating source-generated surface wavetrains in a set of seismicdata traces. According to the method, the seismic data traces are Fourier transformed with respect to time to determine the frequency components of the surface wavetrain. A phase matching operation is then performed using estimates of the wavenumbers for each of the frequency components to approximately align the surface wavetrain in the seismic data traces. Next, a spatial low-pass filter is used to remove the approximately aligned surface wavetrain. Finally, the phase matching is removed and an inverse Fourier transformation is performed to return the seismic data traces to the time domain.

Abstract: A structure of arranging an vehicle occupant protecting apparatus for an automotive vehicle, which can prevent a pillar garnish from scattering when an air bag installed in a front pillar portion is expanded, is provided. An air bag 16 is housed within a space formed by a front pillar main body 38 and a pillar garnish 40 in a front pillar portion 20. When the air bag 16 expands, the pillar garnish 40 is pressed by an expanding pressure of the air bag 16, so that an opening for expanding the air bag 16 is formed between the front pillar main body 38 and the pillar garnish 40, and the air bag 16 expands into a vehicle cabin through the opening. Since a non-expanding portion is formed at the air bag 16 and a hinge portion 46 is formed at the pillar garnish 40, the expanding pressure applied to the pillar garnish 40 when the air bag 16 expand is low, so that the pillar garnish 40 can be easily opened through the hinge portion 46.
